摘　　要：采用酸法提取虾壳钙,并用高锰酸钾滴定法测定虾壳中可溶性钙的含量。采用响应面法分析不同的酸、酸的浓度、提取温度、反应时间对可溶性钙提取的影响。结果表明:钙提取的最佳工艺条件是:盐酸浓度2.5mol/L,盐酸用量2 mL,提取温度75℃,反应时间1 h。用高锰酸钾滴定法测得虾壳钙含量最佳溶出率为9.4%。To take full advantage of the rich resources of shrimp shell, by using acid method to extract calcium in shrimp shell and with potassium permanganate titration method to determine the content of soluble calcium in the shrimp shell. Using response surface to analyze different acids, acid concentration, extraction temperature, the reaction time for the impact on soluble calcium extraction. The results showed that： the extraction of calcium optimum conditions were as follows： the concentration of hydrochloric acid 2.5 mol/L, the dosage of hydrochloric acid 2 mL, the extraction tempera- ture 75 ℃, the reaction of time 1 h. Using potassium permanganate titration measurement of soluble calcium content in shrimp shell of the best dissolution rate was 9.4%.
